How do I make a pointer point to the current running level if each level is its own class?

Question

I'm hard-coding my levels and coding each level in its own class...The problem is that I need to have a pointer that points to the class of the current level. I don't know how I would go about doing this. I ideally want to have a vector that stores the levels, and I'm working on a level managing class to load, update, draw, and unload the levels in.

Answer 1

If your level classes have a common Base class you can just create a pointers to it:

class Level {
    virtual void func1()
    //...
    virtual void funcN()
}

class Level1: public Level {
    virtual void func1()
    //...
    virtual void funcN()
}

class Level2: public Level {
    virtual void func1()
    //...
    virtual void funcN()
}

Vector<*Level> levels;
levels.append(new Level1())
//...
levels.append(new LevelN())

It would be a bad design to have separate classes for each of the level and will also duplicate your code. Why can't you change the level specific values before starting a new level (have them stored in as some constant or in text file).
